How do you generate random numbers in a digital circuit? - created digital numbers
I have the cheapest and easiest way to know in order to create random bits. I design a game that is coincidental, "he asks. Is there a kind of IC is to do this for me?

Created Digital Numbers How Do You Generate Random Numbers In A Digital Circuit?

You can pseudo-random sequences together with a shift register and EORing long pieces to create the entry. This may also be implemented in software, if you use a microprocessor.
The only way to really * is * random sequences to obtain a truly random phenomenon, such as radioactive decay, chemical reaction or use - probably easier - with the white noise.
Reverse an LED or base-emitter of a transistor, which comes in a Zener as "constant voltage" state somewhere 5 to 6 volts. However, when displayed on an oscilloscope and is not very consistent at all, but it is superimposed on a lot of noise! You can simply use the capacitive couple to an amplifier. Add a simple open-collector transistor in the output of op-amp to achieve this with a pull-up resistor to an appropriate level of logic.
Be aware that some random numbers are difficult to obtain. All random number generators require a seed value, and these provisions apply to this number to generate the next number.
One way to improve the farm family must be given to a different seed value each time. Sometimes this can be integrated with a clock, or time of day are performed on a computer. Use the time in seconds. Others use a noise generator.
Search for "random number generator" and you will find.
Here is one:

I'm trying to low-end PIC processors. They are inexpensive and very versatile.
